Our Sustainability Approach

Sustainability isn’t just a word at Martin Marietta. It’s the embodiment of our
commitments to creating value for all of our stakeholders – including our employees,
customers, communities, vendors and investors. Sustainability is a core value at Martin
Marietta and, both in the quarry and the boardroom, stands at the heart of every

Company decision. As an organization reliant upon the
Earth’s natural resources, our sustainability approach
helps us remember that our purpose is to bring value
to all Company stakeholders. Our pledge is to protect
and enhance the environment while creating the

products that build communities. As an organization
built upon the strength of its employees, our approach
also reflects that we care deeply about their safety,
well-being, and being able to welcome and include a
diverse workforce.
